If you're moving from the ESX to ESXi architecture, the only method for upgrade is a fresh install.

I have done this 3 times now with a good bit of success. You shouldn't have to worry as much about reconfiguring anything on your ESX servers if you use the functionality built into the update manager.

I figured it would take between a half a day to as much as an entire day to: backup the db, upgrade VirtualCenter and then install and configure vSphere (networking, HBA scans, etc.) on each of the seven physical hosts (Dell R170s, btw along with iSCSI EqualLogic PS6000xv arrays). But, scripting the deployment will save hours of time and prevent inevitable human errors on my part. I think scripting as much as possible is the way to go. Since you already have a handy script, I would definitely like to utilize a copy. 8) Thanks! So, have you deployed VMware View for the desktops? How are users accessing these desktops?

One a 12 host cluster running about 500 VMs for virtual desktops and another 3 server cluster running 60 Server based VMs for production and testing. We are currently running the latest version of vSphere (4.1) and are backing it with an EMC array for shared fiber channel storage. Just a quick note on the upgrade and not having an enterprise plus license (or distributed Virtual Switch). You can quickly provision a new host with a script. I currently have one that adds all of our network config and sets up all the port groups, there are over 20 of them, and vSwitches, 4 per host. All you do is tell it what server to run on and it does the rest. Let me know if you would like to have a copy of this script. T.C.
